IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters'Patent and makingpart of the.same.

To all whom it may concern.

Be it known .that I, Jons Homomof the city, county, and State of NewYork, have invented a new and improved Lamp; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the ac companying drawings, and to the letters ofreference marked thereon, making a part of this specification. 7

This invention relates to a new and improved lamp, applicable, chiefly,to what is generally termed and known as theargand burner, and which isprcvided with an elevated fountain or reservoir, to supply the flamewith oil under static pressure.

My invention consists in a certain modification in the construction ofthe drip-cup of suchburners, as hereinafter fully shown and described,whereby the wick may be light-ed, by introducing a taper or torch upinto and through the body of the burner from the underside of the same,so that the necessity of removing the glass chimney and shade, isentirely obviated.

My invention also consists in providing a convenient place in the lamp,for the reception of the taper or torch, when not in use, and, also, inthe applicacation to the lamp, of a matchbox, all of which parts, withtheir construction and advantages will be hereinafte-r set forth.

The accompanying drawing represents a side sectional elevation of myinvention.

A represents the base, which supports the lamp, and Bis a rod, securelyfixed centrally in the base, on which rod the tubular arm 0 is allowedto slide freely up and down, so that it maybe secured at'anydesiredpoint on the rod, by a set-screw.

One end of this arm 0 is connected to and communicates with theoil-fountain or reservoir B, andthe opposite endis attached to andcommunicates with the burner-E, which is constructed on the Argandprinciple.

The arm 0 is so curved or bent, or the fountain or reservoir has such anelevation, that the oil within the latter will be fed to the lamp-wickuntil the fountain or reservoir is entirely empty.

The burner E is. composed of an outer cylindrical shell, (I, havingwithin it a concentric tube, 1), permanently secured at its lower end tothe bottom of shell a, the tube 1) being sutiicientlysmaller than a, toadmit of a requisite space between a and b, to form an oil-supplychamber for the wick c, which encompases tube I), the former wick cbeingattached at its lower end to a thimble, d, which is fitted on tube 11,and has a spiral slot cut in it, to form a lip, 11, to fit into a sunkenscrew-thread, f, on I).

The thimble d is provided with a lateral projection, which passcs'into avertical slot, made in a tube, '5, attached permanently to the upperportion j of the burner, the tube a, passing down into the chamber orspace between a and Zr, and provided with holes, to admit of the oilcoming in contact with the wick.

By turning the top j of the burner, the wickis raised and lowered, toregulate the height of the flame.

.The parts above described are old, and, therefore, do not comprise apart of thls iuvention, but are merely described or set forth, to showclearly the character of the parts hereinafter named, and coasttuting myinvention.

F represents the drip-cup, designed to receive the overflow of oil fromthe 'tops ofthe tubes b and 11, This drip-cup is perforated with holesI, at its top, all

around near its edge, and it is screwed upon'the lower end of shell a,so as to receive all drip from the earterior of a, and, also, all thatwhich passes down within l), the oil which passes down within the latterfollowing, of course, the sides of the same. I

Within the drip cup F there is a fixed tube, m, open at the top andbottom, and having its lower orifice through the centre of the bottom ofthe cup. This tube at extends upward a short distance above the level ofthe top of the cup, and within tube 1), as clearly shown in the drawing,and is suiiiciently smaller in diameter than I), to avoid the drip thatpasses down the inner side of I).

The tube at is one of the principal features of my invention, and admitsof important results being attained, to wit, a taper or torch may beinserted up through the tube on, into and above the top of the wick 0,so that the latter may be lighted, without removing theglass chimney andshade, and further admits, in case the cup F becomes filled with oil upto the holes I, of a requisite supply of oxygen, passing up through m,to supply the flame.

The ordinary drip-cup, having no central tube at, the flame is dependentfor its supply of oxygen through the holes I, and in the event of thelatter being out off or sealed by an excess of oil in the cup, a notuncommon contingency, the smoking of the flame is an inevitable result.

The taper or torch, designated by G, when not in use, is inserted in the'upper part of the rod B, the upper part of B, being tubular, to admitof that result, as shown in the drawing. place for it, and it may bevery readily drawn out for use, and readily inserted after use. I

To the side of the fountain or reservoir D, there is attached amatch-box, H, to hold the matches for lighting the taper or torch.

Having thus described my invention,

This is a very convenient What I claim as new, and desire to secure byLet ters Patent, is-- v 1. Providing the drip-cup F of an, argand burnerwith the vertical central tube in, in the manner substantially as andfor the purpose set forth.

2. The torch or taper G, inserted in the rod B of the lamp, when theformer is used with or applied to 'an argand-bnrner lamp, having thedrip-cup F of its burner provided with a central tube, m, substantiallyas shown and described.

3. The match-box H, taper or torch G, fountain or reservoir D, and theargand burner E, when all are constructed, combined, and arranged toform a lamp andconvenient lighting-apparatus, substantially as hereinshown and described.

The above specification of my invention signed by me, this 6th day ofNovember, 1869.
